The doctor has immobilized my right index finger, and has helped, but the pain is now radiating from the index finger down to the thumb, and feels like that part of the hand is tearing, the muscles feel like they are tearing. I was in a car wreck 7-21-16. What could be causing this? I do not have the money to pay for the answer at this time. Thank you for his time reading my question. My back was broken and not working, so money is very limited.
